A Percutaneous Cross Pinning Method for Supracondylar Fracture of the Humerus : The Significance of Elbow Position during Pinning to Avoid Ulnar Nerve Damage / 대한정형외과학회잡지

The percutaneous pinning is a simple, effective method for the treatment of displaced supracondylar fractures of the humerus in children. But there is some controversy in the number of pins used and the method of pin insertion. The cross pinning method provides more stability at the fracture site but the risk of ulnar nerve damage is higher than in lateral pinning method, The senenty-one displaced extension type supracondylar fractures were treated by closed reduction and percutaneous cross pinning from January 1991 to October 1994. Among them, the medial pin was inserted in elbow extension in twenty-eight cases and in forty- three cases the medial pin was inserted in elbow flexion. Ulnar nerve injury occured postoperatively in six cases, in which the pin was inserted with the elbow in flexion position. These results may suggest that when percutaneous cross pinning method is selected to fix the supracondylar fracture of the humerus, it would be safer to insert one or two lateral pins with the elbow in full flexion position followed by one medial pin in extension position in order to reduce the risk of loss of reduction and ulnar nerve damage.

Reconstruction of Medial Malleolus and Deltoid Ligament using Bone / 대한정형외과학회잡지

We present a case of medial malleolus and deltoid ligament loss with extensive overlying soft tissue defect from crushing injury. The resultant gross medial ankle instability necessitated deltoid ligament reconstruction using a bone-patellar tendon graft.

Reconstruction of Hand and Forearm Injury using Reverse Ulnar Artery Forearm Flap: Six Cases Report / 대한정형외과학회잡지

There are many methods in reconstruction for skin defect in hand and forearm. Among them, reverse ulnar artery forearm flap has several advantages which are versatile, safe and convenient flap. We report 6 cases of our experiences.

Treatment of Traumatic Dislocation of the Elbow Joint / 대한정형외과학회잡지

15 cases of acute dislocation of the elbow were treated at Department of Orthopaedic Surgery, Capital Armed Forces General Hospital, Seoul, Korea during the period of March, 1985. To June, 1986 were analysed. The length of follow-up period ranged from 6 months to 16 months, with a mean of 9 months. The results were as follows; 1. 7 cases had been surgically treated, and they revealed rupture of the medial collateral ligament in all. So, we think that the medial collateral ligament of the elbow plays an important role in elbow stability. 2. The average immobilization period for the patient with non-operative treatm ent was 2 weeks. And normal ran ge of motion was obtained at 8 weeks. So, there was no. significant difference from other reports in the duration of recovery. 3. The period of recovery in operated patients was 14 weeks, and it was 6 weeks longer than non-operatively treated patients. 4. There was no chronic elbow instability in all 15 patients, but 3 cases with non-operative treatment complained of medial elbow pain on vigorous exercise.

Diagnostic Analysis for Meniscal Lesions of the Knees / 대한정형외과학회잡지

We assessed the accuracy of clinical evaluation, arthrography and arthroscopy in the diagnosis of meniscal lesions in ninty knees in which arthrotomy was performed for disabling symptoms after evaluation by these three methods. At surgery, ninty-two menisci were removed, of which seventy-two were abnormal and twenty were normal. In these ninty-two menisci, correct diagnostic rate was made clinically 78%, arthrographically 70% and arthroscopically 86%. Arthrographic diagnosis was least accurate for lesions of the lateral meniscus and arthroscopic diagnosis was least accurate for lesions of the posterior horn of the medial meniscus and peripheral lesions. Based on this study, it was concluded that both the arthrography and arthroscopy are valuable technique for diagnosis of meniscal lesions.

Intraneural Ganglion of the Common Peroneal Nerve: A Case Report / 대한정형외과학회잡지

A case of intraneural ganglion, 5cm×2cm×1.5cm, which was located between the funiculi of the common peroneal nerve was excised completely under the operative microscope. There was no communication with adjacent bursa or joint.
